Although its market share is not increasing as rapidly as it had expected, Navistar has made significant progress in cutting its warranty spend and other costs, and as a result posted a positive income number in its fiscal third quarter, despite lower sales than anticipated.

Lawyers for trucking companies have filed lawsuits in three states against the parent company of International Trucks, claiming Navistar failed to disclose known defects and problems with its EPA 2010 MaxxForce engines.

The U.S. Environmental Protection Agency issued a guidance letter late last year to heavy-duty on-highway engine manufacturers outlining how it intends to determine the physical range of adjustment of diesel exhaust fluid quality for certification testing, according to DiscoverDEF.com.

Navistar will be taking orders within a month for International ProStar+ tractors with a Cummins 15-liter ISX engine and Cummins selective catalytic reduction aftertreatment to meet EPA 2010 emissions regulations. By next May it plans to have available a 13-liter MaxxForce engine with Cummins SCR. The company will roll out both engines in other models in staggered launches throughout next year
